Abstract

A gel is produced by magnetically treating and mixing two solutions and in one embodiment subsequently introducing carbon dioxide gas. The first solution is comprised of water and sodium bicarbonate, and the second solution is comprised of water and sodium silicate. The first solution is passed through a positively charged magnetic field, and the second solution is passed through a negatively charged magnetic field. The two solutions are then mixed together to form a gel. The resulting gel has excellent fire-fighting capabilities because of its high heat absorption and emissive qualities. The gel can also be used to aid in the removal of surface coatings.

Claims

exact text as granted — not AI-modified
I claim:  
     
       1. A method for delivery of fire suppressing material onto a fire, comprising the steps of: 
       providing a first solution made by mixing water with sodium bicarbonate;  
       providing a second solution made by mixing water with sodium silicate;  
       passing said first solution through a positively charged magnetic field and passing said second solution through a negatively charged magnetic field;  
       mixing said first and second solutions to form a mixture;  
       introducing carbon dioxide gas into said mixture of said solutions to form a gel;  
       providing a pressure pump;  
       pressurizing said gel by said pressure pump to approximately 5000 psi;  
       providing a dispersion device;  
       pumping said gel by said pump into said dispersion device; and  
       dispensing said pressurized gel on a fire through said dispersion device.  
     
     
       2. The method of  claim 1  further including before the step of pumping said gel the steps of: 
       mixing a surfactant with said mixture; and  
       forming a foamed gel for delivery onto said fire.  
     
     
       3. The method of  claim 1  further including the step of adding water to said gel to liquefy and return said gel to a liquid state. 
     
     
       4. A method for producing a fire suppressant for use in dousing a fire producing carbon dioxide, comprising the steps of: 
       providing a first solution made by mixing water with sodium bicarbonate;  
       providing a second solution made by mixing water and sodium silicate;  
       passing said first solution through a positively charged magnetic field and passing said second solution through a negatively charged magnetic field;  
       mixing equal parts of said first solution and said second solution together to form a mixture; and  
       allowing the mixture to stand and set, thereby forming a gel having fire suppressant properties.  
     
     
       5. The method of  claim 4  further including the steps of: 
       spraying said gel on said fire;  
       allowing said gel to mix with said carbon dioxide to further suppress said fire.  
     
     
       6. The method of  claim 4  further including the step of: 
       introducing a surfactant into said mixture to form a foamed gel.  
     
     
       7. The method of claims  4  further including the step of adding water to said gel to liquefy and return said gel to a liquid state. 
     
     
       8. A chemical process for producing a heat-absorbent material comprising the steps of: 
       providing a first solution made by mixing water with sodium bicarbonate;  
       providing a second solution made by mixing water with sodium silicate;  
       passing said first solution through a positively charged magnetic field and passing said second solution through a negatively charged magnetic field; and  
       mixing equal parts of said first solution and said second solution together to form a mixture; and  
       allowing the mixture to stand and set, thereby forming a gel having heat-absorbent properties.  
     
     
       9. The method of  claim 8  further including the step of adding water to said gel to liquefy and return said gel to a liquid state.
